A man will be imprisoned in a room with a door that's unlocked and opens inwards; as long as it does not occur to him to pull rather than push.
Ludwig Wittgenstein imprisoning quote

If the word has the potency to revive and make us free, it has also the power to blind, imprison, and destroy.
— Ralph Ellison

You can chain me, you can torture me, you can even destroy this body, but you will never imprison my mind.
— Mahatma Gandhi

Under a government which imprisons any unjustly, the true place for a just man is also a prison.
— imprisoning quotation by Henry David Thoreau
